Additional information

The CRC Handbook (Lide, 2008) is peer reviewed and is considered reliable and suitable for use as the key study for this endpoint. This value is consistent with the value cited in the EU RAR (2002) for 1,3-butadiene. The Merck Index (2006) has a value of -4.5°C which is also taken from a peer reviewed handbook and supports the value reported in the key study.
